How is the diffusion coefficient defined

      I need to set the diffusion coefficient of oxygen in carbon dioxide in oxygen-enriched combustion, and I didn't find a way to set it.
      Please kindly help me
      Detailed steps would be great!
      Thanks for your help.

      It's in the Species>Mixture panel.

        hi

        thanks for your help

        But I didn't find this option in either panel (create/edit material→mixture and species model→species transport)

        Can you give more help? Thanks a lot!

      Turn on species transport first, then it should be in the Mixture-thread species panel. Mass diffusivity at the bottom.
